Bagasse pith was tested for its ability to remove cadmium and lead ions from aqueous solutions under two modes of operation, i.e. in batch systems and continuous flow systems. Time dependency experiments showed a very rapid adsorption of these cations by bagasse pith. Thus, 62% of cadmium ions and 84% of lead ions were taken up by the bagasse pith at pH 6 and ca. 99% of each cation was recovered by treatment of the pith with 0.1 M HCl. The breakthrough capacity, Q0.5, the number of theoretical plates and the theoretical plate height were calculated. The capacity of bagasse pith was found to be 6.2 and 8.5 mequiv./g for cadmium and lead ions, respectively. The feasibility of using bagasse pith for cadmium and lead ion removal from wastewater streams was addressed.

Abstract Contamination of heavy metal ions in soils has proved to be a significant concern and it poses many health risks. Conventional methods which was used for the identification and detection of heavy metals were non portable and not suitable for onsite applications. The proposed work is to design a low cost electronic circuit for the detection of cadmium and lead ions in soil sample. A screen printed electrode and a Glassy Carbon electrode are interfaced with a designed circuit for electrochemical analysis. Anodic stripping voltammetry is the theory behind the metal ion detection process. Based on the current peaks observed in voltammetry process, the presence of lead and cadmium in given sample can be determined. A voltage controlled circuit is designed to perform the functions of Ec-Lab which makes this system portable. The results are compared with that of the potentiostat device to evaluate the accuracy of the designed circuit.
